Inclined Handle Switch Panel for Tilted Electric Work Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric work equipment, such as brush cutters, lacks improved operability and visibility when the operator is working while tilting the equipment, particularly in scenarios where the work tool is not oriented vertically.
Innovation Solution
The switch panel is designed to be inclined downward from one side to the other, with the power switch and LED light positioned to enhance visibility and operability when the equipment is tilted, allowing the operator to easily grasp the switch position and status without overlapping with the trigger lever.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the switch panel is positioned on the upper surface of the handle, then the operator can easily access the power switch, but the visibility and operability are poor when the equipment is tilted
Solution Approach 1:
The switch panel is designed with an inclined surface rather than a flat surface, changing the dimensional orientation to accommodate both accessibility and visibility requirements during tilted operation
2Loss of information
If the indicator panel faces the operator in normal position, then visibility is improved, but operability is not improved when working while tilting the equipment
Solution Approach 1:
The indicator panel is positioned on an inclined surface that rotates with the equipment tilt, maintaining proper orientation relative to the operator's line of sight during tilted operation
Solution Approach 2:
The switch panel and indicator panel are integrated on a movable inclined surface that dynamically adjusts its orientation based on the equipment's tilt angle, ensuring consistent visibility and operability
